Application on May 16.1907. Serial in. 27mm.

To all 'ZLZZ-O'fit may concern:

Be it known that l, EDWARD RENNIE, a. subject of the King of Great Britain, resid ing at Halifax, eoun tyof Halifax, in the Province of Nova Scotia, Canada, have invented certs-in new and useful Improvements in Sl1oe-lieel Attachments; and I do hereby declare that the follewin is 21, full, clear, and onset description of the in'w-intion, such as will enable others skilled in the art to which it aopertains to make and 1 'se the some.

plate to be secured to the shoe with. means for retaining a, nut adopted to receive the bolt carried by the plate in the heel; and, my invention consists of the construction,

-'coinhinetiolilinnd arrangement of parts, as

herein illustrated, described and claimed.

in the ecconuenying drawings, forming port of Lliiseupplicetion, l have illustrated one form of embodiment oi my invention, in which drawings similar reference char cters designatecorrespondingparts, and in which:

Figure l. o longitwlinel vertical section through c heel and ill; immediately c0n-.

nectei ports, and showing in side elevation the outline of a, shoe; Fig. is at side clevetion of the zii t ching pistes; 3 e, L view of the pistes in their relative {I position; and, Fig. l is an inverted pron view of the plates.

Referring to the rfl rewings, .1 dcsigsmtes shoe, to which secured a plate 2, having the spurs 3 turned up from. its edges. The plate is adopted to he secured to the shoe by L means the screws 4. The pinto 2 is provid=' I h u countesunk central squared o and hold against not 5 is held from .i gs 7, struck projectmlluited to recei 1c The adapted to receive the socket 5, and hes embedded therein a plate .10, having a central squared socket l1 struck up from its body, and adapted to receive the squared head 12 of a bolt 13, which bolt extends through the socket into the nut 6. The bolt 13 being placed in engagement with the nut 6 and the heel rotated, the heel is brought firmly up against the bottom of the shoe 1, so that the socket 1.1 bears against the socket 5 heel firmly held in position by means of the bolt 13 and the nut 6. The nut 6 is kept from rotating by the rectangular shape of the socket 5, and the bolt 13 is held from rotor tion with relation to the plate 10 by means of the squared socket 11, in which is disposed the head 12 of the bolt.

To prevent rotation of the heel 8 after it is in locked position, a stud 14 is carried by the plate 10 adjacent its forward end, and is ads )ted to work into an opening 15 formed in the upper plate 12. To remove the heel after the stud 14 has engaged in the opening 15, the resiliency of the heel permits a slight movement away from the shoe, so that the stud 14 may be disengaged and the heel rotated to disengage the bolt 13 from the nut 6.

l'leving thus fully described my invention, What it claim as new, and desire to secure by Letters Patent, is:-

1. in combination with a heel, an upper pie to provided with a socket having inwardly the soclict beneath the lugs, means for se curing the upper plate to a shoe, and a co operating holt secured to the heel.
